Blender not registering Keyboard and limited Mouse Input
Thank you for stating your question clearly.

Go to c://users/yourmachine/application data/roaming/blender foundation/blender/28 &lt;-- this last folder should be the one with old preferences and is conflicting with other 2.8 installations. Delete it.

Run Blender 2.8 choose your default selection click but DO NOT change keyboard layout.

Your Blender 2.8 version should be up to date (daily developer version or DD).

Dowload Blender 2.8 DD. Unzip and run from the unzipped folder. Your configs should be reset to defaults and you should have  no trouble driving Blender 2.8

And oh! please, please, close the antivirus totally and make sure the application is not firewalled on your windows configuration. Give firewall permissions to execute 2.8

Thank you for your consideration to select this as the answer.
